14 Claims.

The objects of this invention are:

l First, to provide a new and improved cord or edge roll for use onfurniture or the like.

Second', to provide such a cord or edge roll 5 that is easily andquickly made.

Other objects `and advantages pertaining to details and economies ofconstruction and operation, Will appear from the description to folylow. A preferred embodiment of my invention l is illustrated in theaccompanying drawing, in

which:

Fig. 1 is a perspective sectional view of my edge roll in the process ofmanufacture.

Fig. 2 is a perspective sectional View of my finished cord or edge roll.

Fig.` 3 isa perspective sectional View of a different form of my edgeroll.

The parts will be identied by their numerals of reference which are thesame in all the views.

The edge roll is formed from any resilient fibrous material such as juteor hair or wadded cellulose or the like. This is illustrated at l. Twobats of jute or the like are run through forming dies to form the cords2 and 3. These are preferably formed by folding a bat on itself asillustrated to give a proper cylindrical form. The cords are formed informing dies and are run from the forming dies to a braiding machine.These cords are disposed longitudinally together and are run through thebraiding machine Where the braided threads 4 are wrapped around the twocords, holding them together.

It willbe noted that when the two cords are wrapped by the braidedthreads the threads are not in contact with the cords at their line ofcontact 5 but extend from the surface of one cord to the next withoutfollowing the exact contour of the two cords. In order to tighten thethreads and to form a reinforcement at the line of contact 5, I providea fabric strip 6. It will be noted that the cord 3 is smaller than thecord 2 and the fabric strip 6 is placed around the smaller cord 3 buthas its edges overlapping the line of contact 5.

A row of stitches 1 is run longitudinally of the cord, passing throughthe fabric 6 on both sides of the edge roll and passing through thelarger cord 2. If desired, these stitches may also pass through the edgeof the smaller cord 3. This pulls the braided threads 4 down intocontact with the two cords at the line of contact 5 and tightens thethreads 4 to form a solid edge roll and the smaller cord forms anattaching web.

If desired, a second line of stitches 8 may be run passing twice throughthe fabric 6 and through the smaller cord. This has a compressing effectand makes a firmer attaching web.

In Fig. 3, instead of using a single strip E I use a pair of fabricstrips 9 and lil. These strips are disposed on opposite sides of theedge roll and overlap the line of contact 5. A row of stitches il passesthrough each strip and through the larger cord '2 and may also passthrough the smaller cord. A second row of stitches I8 passes throughboth strips of fabric and through the smaller cord, thus compressing itto form a satisfactory attaching web. i

It will be seen that this cord has braided wrapping threads 4 which aresufficient to hold the resilient material in its desired form. Thesethreads do notfurnish a satisfactory reinforcing if stitching is to beput through the cord or is to be used in attaching the edge roll tofurniture. 'Ihe fabric strips 6, or 9 and I0, serve this purpose andalso tend to tension the braided Wrapping threads 4to make a tightlyheld roll.

The roll may be easilyand cheaply made by first feeding the jute makingup cords 2 and 3 to forming dies and then feeding the device directly toa braider. The braided cord is then fed directly through a forming diewith the fabric strip 6 or thestrips 9 and I0 and as the article comesthrough the forming die with the strips of fabric in place` the lines ofstitches 1 and or il and I8 are made on a sewing machine.

The final product is an edge roll with reinforcing placed where it isneeded, saving the expense of additional fabric where it is notnecessary. The fabric performs a very satisfactory function between thecords 2 and 3 and the attaching i pointed out in Having thus describedmy invention, what I Y 2.
